Women’s Active Underwear That Stays Put: No Ride-Up, All Day Comfort

If you’ve ever had your workout interrupted by underwear that rides up, pinches, or shows through leggings — you’re not alone. In fact, the #1 failure mode for active underwear is ride-up, followed closely by lack of seamless comfort and quick-dry performance.

At SPANX, we believe activewear should help you move — not distract you while you do it. That’s why we designed women’s active underwear that works as hard as you do: the invisible comfort layer that stays put, smooths seamlessly, and disappears under everything.

The Underwear Problem No One Talks About

When it comes to underwear for movement, women want one thing above all: to forget it’s there. But traditional active underwear often falls short. From shifting fits to visible seams, there are a few familiar frustrations that keep showing up — and showing through:

• Ride-up during runs, squats, or yoga flows.
• Visible lines under leggings and shorts.
• Trapped heat and moisture from non-breathable fabrics.
• Uncomfortable waistbands that dig or shift mid-workout.

Our solution? A collection engineered to solve all of that: no tugging, no adjusting, no second thoughts.
